I stayed one month at Sasi's. Everything was perfect. Great, super convenient location, right next to the BTS station Bang Chak. The pool is stunning, the gym had enough equipment to keep me fit. The last day I found out, that there's even a private basketball court. The apartment itself is beautifully decorated and furnished. She just installed a new WiFi router before I arrived. You now get super high speed and stable internet, so you can work easily. Stream Netflix, move big data if you may want. The view from the place is also really nice, especially while working from the desk. Sasi was always available and even passed me her line contact for even faster communication, but I only needed her help once for some minor thing with the kitchen. I'd definitely recommend this place and will book it, whenever I go back to Bangkok. Thanks for everything, Sasi!
